JOSEPH B. MOWRY, OF MANSFIELD, OI-IIO, ASSIGNOR OF ONE-HALF TO J. F. STINE, OF SAME PLACEL BRICK-MOLD.

SPECIFICATION forming part of Letters Patent No. 503,66*?dated August 22, 1893.

Application filed November 15, 1892. Serial No. 452,085. (No model.)

To aZZ whom t may concern.-

Be it known that I, JOSEPH B. MoWRY, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Brick-Molds; and I do here- .by declare the following to be a full, clear,

and exact description of the invention, suchas will enable others skilled in the art to whichy 1t appertains to make and use the same.

My invention relates to improvements in mold boxes for `brick machines, and the ob` ject of the invention is to provide a box of slmple and strong construction, the lining of which will be held rmly in place and can be easily removed by simply detaching one side of the box.

With these ends in view my invention consists of a mold box formed by two parallel longitudinal plates or sides and twol or more parallel transverse partitions or division walls provided at their ends with suitable tenons which extend through apertures or mortises formed in the parallel longitudinal plates or sides and are held iirmly in position therein.

My invention further consists in the comb ination with such a mold box of metallic llning plates arrangedV Within the box, the plates adjacent to the longitudinal walls of the box having formed in their edges notches corresponding in number and aligning with the mortises or apertures in said walls of the box and the plates adjacent to the transverse Walls or sides of the box being provided with a series of projecting lugs or ears which align with the tenons on the transverse walls and extend into the apertures or mortises in the longitudinal plates when the various parts of the mold box are assembled together.

My invention still further consists in the peculiar construction and arrangement of parts as will be hereinafter more fully pointed out and claimed.

In the accompanying drawings-Figure l is a perspective view of a mold box constructed in accordance with my invention, one of the longitudinal sides being removed. Fig. 2 is a sectional plan view of the same. Fig. 3 is a detail view of one of the transverse lining plates; and Fig. 4 is a detail view of one of the other lining plates.

Like letters of reference denote corresponding parts in the several figures of the drawings, referring to Which- A, A', designate the two parallel longitudinal plates forming the front and rear sidesor Walls of my improved mold box and said plates may be of any desired size and thickness according to the size of the machine in which 'the mold box is intended to be employed.

The plates A, A', are connected at suitable intervals by transverse vertical partition or division plates B to form any desired number of compartments within the mold box.

The transverse division plates B are provided at their ends With a series of integral projecting tenons C the outer ends of which are, preferably, reduced and threaded as shown in Fig. l. The tenons C extend or project through suitable apertures or mortises formed in the plates or Walls A, A', and on the outer threaded ends of said tenons are screwed nuts D by means of which the plates A, A', and B are held firmly in position.

The interior of the compartments of the mold box are lined by metallic lining plates preferably of steel. The plates E adjacent to the plates A, A', of the box are provided in their edges with a series of notches Ve corresponding in size, number and position with the mortises in said walls with which they align and the lining plates F adjacent to the transverse division plates B are provided at their ends with a series of projecting lugs or ears which conform in number and height to the tenons on said division plates. The tenons C, which are preferably of greater thickness than the body of the plates B, are cut away or reduced on their side faces to form shoulders G against which the ends of the ears or lugs f bearas shown in Fig. 2.

In assembling the various parts together to form a mold box the tenons C at one end of the division plates B are passed through the mortises in the plate A and the nuts D screwed on the outer threaded ends thereof to firmly connect said plates A and B. The lining plate E adjacent to the Wall A of the box is then placed in position, the notches e in the sides thereof aligning with the mortises in the wall A. The side lining platesF are then IOO placed in position, the ears or lugs f at one end thereof eitein g the notches esand aligned apertures or inortises in the wall "A, The other lining plate E and side plate A are then fitted in position and said plate A firmly connccted vto the division plates B by means of nuts s'cr'ewedron Athe outer threaded ends ofi tures or mortises in the wall A.

It will be noticed that the lining plates E, F, operate to hold each other in pl-aceandfthat both lining plates and division Walls are held in place by the nuts D screwed on the outer-ends ofthelte'non-SCC. 4 'l It will thus be scent-hatl have provided al, simple and strong mold box consistingof a` series of compartments open at both top-and bottom'an'dboun'ded by smooth metallicwalls. V

To replace the metallic-lining platesEFL it is only necessary to removev Y'eithe'rao'ne ofgi then parallel I longitudinal 'plates `A, A', when anjd replaced by new ones. y

In vthe drawings extending'the plates A, A', a'nd I'irovidingad-g' dition'al division plates 13,: any desirednu'm-lber-ot compartments can befornie'd. V

Having 'thus' fully described rny invention; what I claimas'new, and desire'toisecureby `1. ,A mold box foi-med by two parallel sidey plates ,provided with aligned mortises,y trans-- verse-'division walls or v`plates ,provided-width? integral threaded tenons adapted to enter the;v niortises in the-sideplate's, lining platesjar-l" ranged in eachcompartment of the box said platles'fbeinggfprovided `with notchesA and ears or lugs corresponding'tothe mortises in thel and operating to hold bot-h the division walls the tenons C which extend through'the raper-ir and liningplates in position, substantially as described.

2. A mold box consisting of the parallel fplatesA, A', provided with aligned series of mortises, transverse division plates B proYided with tenons adapted to enter the mortlses f 'intrh-e'pliates A, A', and Idivide-thev mold box intoany'desi-red number of compartments, metallic lining plates arranged in each compartment of the mold box, \,the,1ining Y,plates adj acentl tov tliegplat's A, 2X', b i i 'provided 1in-their Vside edges; with notchesfwhich align with V.the zn'i'ortises ,in the plates A, -"'A, and the vl lining ,plates adjacent tothe 'diyi'sion j. plates lsaid liningplates lcan be readily withdrawni lates, said' liningplates" being; held'from ie'ndviise; movement lbly lugs or shoillld'exs "formed on "the fte'n'cmsgy C, :and nuts screwed fonV the ,cuter endsof the ten'on'sCandgopelating to hold both the*divisio'n"platesandlin'ing plates in Iposition, 1substantially as described.
